  During the past year, John P. Cunningham retired from active management
  of the Company.  He has served as the President since 1972 and we would
  like to thank him for his many years of dedicated service and look forward
  to his continuing involvement as a member of the Board of Directors.

  TO OUR SHAREHOLDERS




  With an increase in sales of 8 percent, net income, excluding the
  1998 gain on the sale of a foreign subsidiary, declined by 6 percent.

  This year we had to completely rebuild the foundry at our extrusion
  operation  in California.  During the foundry renovation, scrap
  normally converted into billet internally was converted by an outside
  vendor, significantly increasing unit material cost.  Profitability
  was also hampered by severe mechanical breakdown of equipment at our
  extrusion plants in both California and Texas impacting sales for
  both the Extrusion and Commercial Products Groups.  Additional
  increases in costs were incurred working overtime to keep the
  available presses running longer hours.

  It should be obvious that your management is not pleased with these
  results and we are doing everything in our power to re-establish a
  pattern of consistent, profitable growth.  In order to achieve this,
  some major changes have been made at the corporate office and in the
  management of our core business units.  The position of President and
  Chief Operating Officer of the Company is now filled by Mr. J.D.
  Williams who had an excellent track record with the Company while in
  charge of our Commercial Products Group.  Mr. Williams has appointed
  new group operating executives to head each core business group and
  has empowered them to manage their respective product groups as they
  deem necessary to meet the goals as set forth in their group business
  plans which are orientated toward growth.

  The corporation is committed to becoming a low cost producer by
  implementing modern lean type manufacturing concepts throughout each
  operation.  Major capital expenditures will be required at each
  subsidiary for modernization upgrades which will increase production
  capacity and improve quality.

  Our Research and Development Department has developed new products
  for the Commercial and Residential Products Groups and we expect to
  see favorable results as these new products are introduced in the
  market.



  <PAGE>

  While we are committed to improving existing operations, we are
  also focusing on products within our core business units which will
  provide the best return and position the corporation for growth.
  We are actively pursuing additional growth through acquisitions of
  companies manufacturing products complementing those currently
  marketed by our existing subsidiaries.  Preliminary discussions are
  already in progress with several of these companies.

  The company s financial health continues to be excellent with
  Shareholders  equity rising to $128.7 million or $29.99 per share.
  The balance sheet continues to be very strong with total assets at
  yearend increasing to $153.7 million with no long-term debt.
  Working capital at June 30 was $69 million and our current ratio
  was 4.4 to 1.  Capital expenditures for next year are currently
  projected to be around $18 million with a significant portion for
  the continuation of production equipment upgrades at the two
  extrusion facilities.

  As we embrace the changes previously discussed, we embrace the
  opportunity for renewed growth and better competitiveness.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Significant Changes in Results of Operations
1999 vs. 1998
Net sales for fiscal 1999 increased by $18,817,000 or 8.3% from net
sales of fiscal 1998.  The increase primarily consists of a
$12,004,000 or 11.0% increase in sales of commercial products,
reflective of continued strong demand for the Company's exterior
products throughout most of its marketing regions.  Sales of
residential products increased $3,478,000 or 7.0% attributable to the
strong California housing market.

Gross profit decreased to 30.0% of sales in 1999 as compared to 30.6%
in 1998.  The decrease is largely attributable to higher labor and
overhead unit costs incurred at our extrusion operations resulting
from  equipment failures and mechanical breakdowns coupled with
reduced selling prices.

Selling, general and administrative expenses were 23.3% of sales in
1999 as compared with 22.7% in 1998.  The $5,772,000 increase in
current year expense primarily reflects costs incurred in support of
the increased sales volume.  The other component of the change relates
to recruiting and relocation costs associated with realigning and
enlarging  operating group management teams.

The decrease in interest income relates to the significantly decreased
level of funds available for investment during the current year due
primarily to increased capital expenditures.
<PAGE>
1998 vs. 1997
Net sales for fiscal 1998 increased by $1,763,000 or 0.8% from net
sales of fiscal 1997.  The sale of the Company's Dutch subsidiary,
Eland-Brandt BV during the second quarter significantly impacts period
comparisons.  The exclusion of Eland-Brandt BV from the comparison
shows an increase of $11,120,000 or 5.2% for the year.  The sales from
ongoing operations primarily consist of a $6,808,000 or 6.7% increase
in sales of commercial products resulting from increased demand for
interior and exterior commercial products in the southern region of
the United States.

Gross profit increased to 30.6% of sales in 1998 as compared to 28.0%
in 1997.  This increase is primarily attributable to increased margins
in the Aluminum Extrusion Group resulting from labor and overhead
efficiencies attained through higher production volume.  Also factors
were the prior year inventory and asset writedowns related to the
purchase of Altura and the prior year additional workers compensation
insurance expense related to a major industrial accident during that
year.

Selling, general and administrative expenses were 22.7% of sales in
1998 as compared with 23.5% in 1997.  Expenses in the current year
have decreased by $1,280,000, which reflects the elimination of costs
due to the sale of Eland-Brandt BV.  Other components of the change
include increased selling and marketing costs during the current year
and decreased costs related to certain nonrecurring charges in the
prior year.

The increase in interest income relates to the significantly increased
level of funds available for investment primarily resulting from the
cash provided by operations.
<PAGE>
Inflation
Because the Company's products are predominately made-to-order, the
impact of inflation on operating results is typically not significant.
The Company attempts to alleviate inflationary pressures by increasing
selling prices to help offset rising costs (subject to competitive
conditions), increasing productivity and improving design.


Liquidity and Capital Resources
Working capital at June 30, 1999 was $69,030,000 compared to
$72,170,000 at June 30, 1998 and $65,820,000 at June 30, 1997.  The
ratio of current assets to current liabilities was 4.4 at the end of
1999 compared to 4.7 at the end of 1998 and 3.9 at the end of 1997.
The Company continues to be in excellent position to meet its short-
term operating and discretionary cash requirements.  Funds in excess
of current operating requirements are invested in short-term interest-
bearing instruments.

Capital expenditures for property, plant and equipment of
approximately $15,059,000 in 1999, $6,837,000 in 1998 and $7,508,000
in 1997 were financed through internal cash flow and cash reserves.
Additional cash flows include the 1999 fiscal year expenditure of
$1,300,000 for an acquisition (see Note 9), the 1998 fiscal year
receipt of $1,021,000 from the sale of a subsidiary and the  1997
fiscal year expenditure of $6,971,000 for two acquisitions.  In
addition to the normal annual expenditures for replacement items, the
Company  projects capital expenditures for fiscal 2000 of $18,000,000
for scheduled expansion of production capacity.  The Company
anticipates financing these expenditures through internal cash flow.

The Company had $15,000,000 in available credit at the end of 1999
under a short-term borrowing arrangement with a bank.

The Company's financial condition remains strong.  The Company
believes that its cash, other liquid assets, operating cash flows and
borrowing capacity, taken together, provide more than adequate
resources to fund ongoing operating requirements and future capital
expenditures related to the expansion of existing businesses.


<PAGE>
Current and Pending Accounting Changes
The Financial Accounting Standards Board has issued a new standard
affecting the accounting for derivative instruments and hedging
activities.  This standard will not change our operating results,
financial condition or disclosures.

Year 2000
The Company utilizes software and related technologies throughout its
business that will be affected by the date change to the year 2000.
The Company performed a review of the software it uses in its business
for year 2000 compliance.  The Company has completed the migration to
compliant releases of its financial and human resources software.  The
Company has substantially completed the implementation of new
compliant operational software which will also enhance manufacturing
information and customer service.  The Company has targeted year 2000
compliance by no later than October 1999, and thus has not developed
contingency plans.

The consequences of non-compliance (although the Company does not
anticipate such) by the Company, its customers or its suppliers could
have a material adverse impact on the Company's operations.  The
Company will continue to incur expenses related to these efforts;
however, such expenses are not expected to have a material impact on
the Company's results of operations.

REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Shareholders of
International Aluminum Corporation

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, cash flows and shareholders' equity present
fairly, in all material respects, the financial position of International
Aluminum Corporation and its subsidiaries at June 30, 1999 and 1998, and the
results of their operations and their cash flows for each of the three years in
the period ended June 30, 1999, in conformity with generally accepted accounting
principles.  These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits.  We conducted our audits of these statements in
accordance with generally accepted auditing standards, which require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation.  We believe that our audits provide a
reasonable basis for the opinion expressed above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 1.  Significant Accounting Policies and Procedures

Principles of Consolidation

The consolidated financial statements include the accounts of International
Aluminum Corporation (the Company) and its domestic and foreign subsidiaries.
All significant intercompany transactions and accounts have been eliminated
in consolidation.  Certain reclassifications of prior year information were
made to conform to the current presentation.

Estimates and Assumptions

The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes.  Actual results could differ from those
estimates.

Foreign Currency Translation

Assets and liabilities of the Company's foreign subsidiary are translated
into U.S. dollars at year-end exchange rates and revenues and expenses are
translated at average rates prevailing during the year.  Local currency is
considered to be the functional currency.  Translation adjustments are
deferred into accumulated other comprehensive income, a separate component of
shareholders' equity.  Foreign currency transaction gains and losses are
included in results of operations as incurred.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and marketable securities with
original maturities of three months or less.

Depreciation and Amortization

Depreciation and amortization are provided over the estimated useful lives of
the assets or the remaining terms of the leases, whichever is shorter, using
the straight-line method for financial reporting purposes and accelerated
methods for tax purposes.

The excess of the purchase price over the underlying book value of the
companies acquired is classified as "Costs in excess of net assets of
purchased businesses".  The related amounts of $12,743,000 at June 30, 1999
and $12,169,000 at June 30, 1998 are being amortized using the straight-line
method over periods of up to forty years.  Accumulated amortization totalled
$2,983,000 at June 30, 1999 and $2,418,000 at June 30, 1998.

Long-Lived Assets

Whenever events indicate that the carrying values of long-lived assets
including any related goodwill may not be recoverable, the Company evaluates
the carrying values of such assets using future undiscounted cash flows.
Management believes that, as of June 30, 1999, the carrying values of such
assets are appropriate.

insurance and maintenance.  All facility leases are classified as operating
leases.

Note 8.  Stock Options

The Company grants stock options for the purchase of common stock to certain executive and managerial
employees under the Company's 1991 Stock Option Plan.  Options have an exercise price equal to the market
price of the stock on the date of grant, a term of ten years and generally become exercisable over a five
year period.  The Company applies APB Opinion 25 and related Interpretations in accounting for the plan,
accordingly, no compensation cost has been recognized for those stock options. There would have been no
material change in reported net income and earnings per share had compensation cost been determined based
on the fair value at the grant dates as prescribed by SFAS 123, "Accounting for Stock-Based Compensation".
The transactions for shares under options for the three years ended June 30, 1999 were:

Note 9.  Acquisitions and Divestitures

During the current year, the Company formed a wholly-owned subsidiary named
International Window-Colorado, Inc. (IW-CO) which became a member of the
Residential Products Group.  On October 1, 1998, IW-CO completed the
$1,300,000 cash purchase of selected assets and liabilities of a Denver,
Colorado residential window and door company.  The estimated fair value of
the net assets acquired was $726,000.  The $574,000 excess of the purchase
price over the estimated fair value of the net assets was allocated to
goodwill and is being amortized on a straight line basis over 15 years.
Proforma information has not been presented as it is not materially different
from historical results.

During the second quarter of the prior year, the Company sold it's Dutch
subsidiary, Eland-Brandt BV, for approximately $1,021,000 in net cash
proceeds.   The sale generated a pretax gain of $1,235,000 (after-tax gain of
$1,156,000 or $.27 per share), including the recognition of $2,145,000 of
previously deferred cumulative translation adjustment.  The gain had only a
small income tax effect because the Company had not provided benefit for
certain losses accumulated in prior years.  The Company's consolidated
financial statements include the results of Eland-Brandt BV through the date
of disposal.  Such amounts were not material in relation to the consolidated
financial statements.
